Patients with elevated PD-L1 expression on TC after neoadjuvant chemotherapy showed a trend to have a shorter progression-free survival than patients without elevated PD-L1 expression on TC, although the difference was not statistically significant in multivariate analysis (hazard ratio=2.38, 95% confidence interval=0.99–5.73, P =0.053).
